1. Connect the SS to the UE antenna connectors as shown in [6] TS 38.508-1 A.3.1.2.1 for SS diagram and A.3.2 for UE diagram.

2. The parameter settings for the E-UTRA cell are set up according to TS 36.508 [11] clause 4.4.3, and the parameter settings for the NR cell are set up according to TS 38.508-1 [6] clause 4.4.3.

5. Propagation conditions are set according to TS 36.521-1 [10] Annex B.0 and TS 38.521-1 [8] Annex B.0 for E-UTRA CG and NR CG respectively.

For the E-UTRA CC(s) where anchor agnostic apply according to NOTE 4 in Table 7.3B.2.3_1.2.4.1-1, downlink signal level and uplink signal level are set according to Table 4.6-1 and propagation conditions are set according to Annex B, clause B.0 of TS 36.521-1 [10]. Disable periodic and aperiodic CQI reports, disable SRS, set TimeAlignmentTimerDedicated IE to infinity and disable downlink and uplink scheduling, all as per Table 4.6-1 under clause 4.6.

7.8B.2.3_1.2.4.2 Test procedure

1. SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0 and DCI format 0_1 for C_RNTI to schedule the UL RMC according to table 7.8B.2.3_1.2.4.2-1 on E-UTRA CC and NR CC respectively. Since the UL has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.

2. Set the Downlink signal level to the value as defined in Table 7.8B.2.3_1.2.4.2-1. For E-UTRA CC and NR CC where uplink is allocated according to Table 7.8B.2.3_1.2.4.1-1, send uplink power control commands to the UE using 1dB power step size to ensure that the UE output power measured by the test system is within the Uplink power control window, defined as -MU to – (MU + Uplink power control window size) dB of the 4dB below PCMAX_L with PCMAX_L as defined in clause 6.2B.4 for at least the duration of the Throughput measurement.

– MU is the test system uplink power measurement uncertainty and is specified in Table F.1.3-1 for the carrier frequency f and the channel bandwidth BW.

– For NR CC, Uplink power control window size = 1dB (UE power step size) + 0.7dB (UE power step tolerance) + (Test system relative power measurement uncertainty), where, the UE power step tolerance is specified in TS 38.101-1 [2], Table 6.3.4.3-1 and is 0.7dB for 1dB power step size, and the Test system relative power measurement uncertainty is specified in Table F.1.2-1.

3. Set the Interfering signal levels to the values as defined in Table 7.8B.2.3_1.2.4.2-1 and frequency below the wanted signal.

4. Measure the average throughput for a duration sufficient to achieve statistical significance according to Annex G, clause G.2.

5. Repeat steps from 2 to 4, using an interfering signal above the wanted signal at step 3.

6. Repeat steps 2 to 5 for component carriers listed in Table 7.8B.2.3_1.2.4.2-1.
